Which statements are true of solutions? they contain solutes and solvents. they always have only one solute per solvent. their particles must be evenly distributed. they may contain solid, liquid, and gas simultaneously. they are always easy to distinguish from colloids. they are homogeneous matter. they are pure?

answer: the statements which are true for solutions are: they contain solutes and solvents, their particles must be evenly distributed, hey may contain solid, liquid, and gas simultaneously, hey are always easy to distinguish from colloids and they are homogeneous matter.

explanation: a solution is a mixture in which the solute which is present in lower amount is uniformly distributed in the solvent which is present in major amount.

the true statements for solutions are:

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
